In Toronto to promote the debut of her House of Harlow jewelry line at Holt Renfrew, Nicole Richie shows off a few of her wares — and some serious shimmer — before a meet and greet at the store. In Montreal today, the expectant mama is twittering her trip — follow her here.

Nicole, 27, and partner Joel Madden — who just bleached his hair! — expect their second child in late August/early September. The new baby will join Harlow Winter Kate, 15 months.
